After setting up the required configuration for an email (email group, sender, email design, subject line, etc.), you can schedule the email to go out at the date and time of your choice.

Once scheduled, the email moves to the Pending tab. If you choose to cancel the schedule, you can do it here. The email will then move to the Drafts tab.

The same capability is provided when sending event invites and other event-related communication and setting up email automations.
